Effects of collisional ion orbit loss on neoclassical tokamak radial electric fields

Hongxuan Zhu, T. Stoltzfus-Dueck, R. Hager +2

Ion orbit loss is considered important for generating the radially inward electric field $E_{r}$ in a tokamak edge plasma. In particular, this effect is emphasized in diverted tokama…

Verification of a Fully Implicit Particle-in-Cell Method for the $v_{∥}$ Formalism of Electromagnetic Gyrokinetics in the XGC Code

Benjamin J. Sturdevant, S. Ku, L. Chacón +8

A fully implicit particle-in-cell method for handling the $v_{∥}$ -formalism of electromagnetic gyrokinetics has been implemented in XGC. By choosing the $v_{∥}$ -formali…

Constructing a new predictive scaling formula for ITER's divertor heat-load width informed by a simulation-anchored machine learning

C. S. Chang, S. Ku, R. Hager +6

Understanding and predicting divertor heat-load width $λ_{q}$ is a critically important problem for an easier and more robust operation of ITER with high fusion gain. Previous predic…
